Did Amazon do it out of their own volition, or did you instruct them to do it? Also what you're considering fair use, may or may not be fair use. Fair use is a specific exemption made in a specific context. You cannot reapply that exemption in an SaaS context and call it equivalent. You'll have to first demonstrate the legal basis for your claim that the two contexts are equivalent.
Also I do recognize that all of us here are non-experts giving our two cents, so any disagreement we have is TBH inconsequential to what the law actually says and how its actually interpreted! :)
